Optimal PV array configurations for partial shading conditions

Indonesian Journal of Electrical Engineering and Computer Science, 2023
Increasing the effectiveness of photovoltaic (PV) power generation systems is a major barrier to their widespread use. Partial shading conditions (PSCs), which are caused by nearby objects like trees, buildings, and clouds, reduce the energy produced by PV systems and may be mitigated by the reconfiguration of PV arrays.

L-Shape Propagated Array Configuration With Dynamic Reconfiguration Algorithm for Enhancing Energy Conversion Rate of Partial Shaded Photovoltaic Systems

IEEE Access, 2021
Partial shading is an unavoidable factor that reduces the performance of solar PV systems. The PV system receives uneven irradiation due to partial shading which causes the mismatch loss.

Performance of PV array configurations under dynamic partial shadings

EPJ Photovoltaics, 2023
The partial shading effect (PSE) is responsible for most power losses in a photovoltaic (PV) system. By modifying the interconnections between PV modules, called PV array reconfiguration, it is possible to improve the power output under partial shading conditions (PSCs).

Experimental Exergetic And Energetic Analysis of Different (PV) Array Configurations

Engineering and Technology Journal, 2022
It is well known that photovoltaic (PV) can be connected in parallel, series, and parallel series. In this study, four PV panels are connected in four different ways, i.e., 4panels parallel (4p), 3panels parallel*1panel series (3p*1s), 2panels parallel*2panels parallel (2p*2p) connected in series, and 2panels series *2panels series (2s*2s) connected in

Performance investigation of hybrid and conventional PV array configurations for grid-connected/standalone PV systems

CSEE Journal of Power and Energy Systems, 2020
Now a days, the critical challenge in solar photovoltaic (PV) system is to make them energy efficient. One of the key factors that can reduce the PV system power output is partial shading condition (PSC). The reduction in power output not only depends on shaded region but also depends on pattern of shading and physical position of shaded modules in the

Numerical modeling, simulation and evaluation of conventional and hybrid photovoltaic modules interconnection configurations under partial shading conditions

EPJ Photovoltaics, 2022
Partial shading on solar photovoltaic (PV) arrays is a prevalent problem in photovoltaic systems that impair the performance of PV modules and is responsible for reduced power output as compared to that in standard irradiance conditions thereby resulting
